FOLDING PORTABLE WIRELESS UNIT

摘要

Conductive metal frame (1) attached to upper case (9) is electrically connected to hinge metal member (5). Hinge metal member (5) is connected to hinge metal member (8) by rotary shaft (7) in a rotatable manner. Hinge metal member (5), hinge metal member (8), and rotary shaft (7) are made of conductive metal so that electric continuity is obtained at contact points thereamong. Hinge metal member (8) is connected to matching circuit (11) on circuit board (4) via feedpoint terminal (3). Conductor element (14) is connected to a ground pattern of circuit board (4) at a position close to a point at which matching circuit (11) is grounded. The structure as described above provides a folding portable wireless unit that can secure a high antenna performance in a calling state and a waiting state.
